Clear Cache about bigcache

[btesanovic]

Hey @wendigo , thanks so much for fast response, this is perfect !!

[wendigo]

@janisz: onRemove does not make any sense I guess (if you need keys - use iterator before clear()). I agree with you on creating new map and reseting indexes

[wendigo]

I'll try to come up with an implementation

[janisz]

I think we can add this method. But how it should works in details. I assume after calling Clear() we should end up with no entries in cache. Questions we need to answer

1. Are we going to call OnRemove callback for every element in cache
2. Are we going to create new (small) shard queues or just use existing one

In my opinion clear should just delete all entries in maps by creating new map (GC will do the rest) and reset indexes in queue (tail, head, rightMargin, count). OnRemove should NOT be called.

@btesanovic @wendigo What do you think?

Solved @btesanovic. Let me know if it works for you!
